The TEROS 54 is an instrument designed to measure soil moisture. It is used to control the exchange of water and heat energy between the land surface and the atmosphere through evaporation and plant transpiration. The sensor is manufactured, tested, calibrated, and repaired in-house, and comes with a 30-day satisfaction guarantee. It is recommended to use the latest versions of METER software and firmware for the computer or mobile device, products, and sensors.

Before installing the TEROS 54, confirm that all components are intact. You will need dedicated accessories and tools, which are available from METER. In addition, you will need PVC casing or flexible conduit to protect cables, and a level.Determine the desired installation location and choose the best installation method. Please note that the slide hammer is quite loud when being used and also has the chance of pinching fingers. It is recommended to wear proper ear protection to prevent hearing damage and gloves to protect hands from injury when using the slide hammer for TEROS 54 probe installation. METER recommends conducting a system check with a logger prior to installation.To read the full TEROS 54 User Manual, visit metergroup.com/teros54support.InstallationFollow these steps to install the TEROS 54:Prepare Hole: Conduct a system check before going to the field. Auger a vertical hole with the auger. Auger to the desired depth (maximum of 70 cm) in steps to avoid soil compaction. Insert the TEROS 54 probe into the borehole firmly, but carefully.Insert Probe: Insert the tip of the TEROS 54 into the center of the borehole. Push the probe into the borehole only if the soil allows it to slide in easily. If it doesn't go in when pushed, use the slide hammer.Check Sensor and Protect Cables: Plug the probe into the data logger and use the SCAN function in the software to do a quick check of sensor operation. Secure and protect cables with PVC casing or flexible conduit and backfill the trench or hole.Plug Sensor In and Configure Logger: Use data logger software to apply appropriate settings to the sensors plugged into each data logger port.The port configuration is as follows:(+)(-)(+)Port 1Port 2Port 3Port 4Port 5Port 6

Sonex Aerospace, LLC is excited to announce that Navmar Applied Sciences Corporation (NASC) has successfully begun the flight test program for the NASC TEROS Group 4/5 Unmanned Aerial Vehicle technology demonstrator. The flight took place at the NASC Unmanned Aerial Systems Flight Operations and Training Center at the Griffiss International Airport in Rome, NY on January 29, 2020. The TEROS UAV flew for approximately 1.5 hours in both manual and autonomous flight profiles successfully testing the aircraft systems and avionics suite.

Based-upon the popular Sonex Aircraft Xenos Motorglider, its rugged, aerobatic-capable structure enables the NASC TEROS to provide a flexible plug and play payload capability for multiple payloads up to 600 pounds at high altitudes for extended flight durations. The NASC TEROS was designed in collaboration with Sonex Aerospace, LLC and is a Medium Altitude Long Endurance Unmanned Aircraft Vehicle (UAV) capable of operating within the Group 4 and Group 5 UAV classifications. TEROS was designed and built to FAA Part 23 (structure and systems) and MIL F 83691 (flight characteristics) standards.

"The successful flight testing of TEROS is a major milestone for the Sonex companies," remarked Sonex Aerospace CEO Mark Schaible. "This benchmark has major significance with regard to the future of Sonex Aerospace and Sonex Aircraft LLC, promising growth opportunities to take Sonex to the next level of business operations, while continuing to serve our traditional sport aircraft market."

Both series of sensors operate as sub-classes of the SDI12Sensors class. They require a 3.5-12V power supply, which can be turned off between measurements. While contrary to the manual, they will run with power as low as 3.3V. On the 5TM with a stereo cable, the power is connected to the tip, data to the ring, and ground to the sleeve. On the bare-wire version, the power is connected to the white cable, data to red, and ground to the unshielded cable.

Coming from the factory, METER sensors are set at SDI-12 address '0'. They also output a "DDI" serial protocol string on each power up. This library disables the DDI output string on all newer METER sensors that support disabling it. After using a METER sensor with ModularSensors, you will need to manually re-enable the DDI output if you wish to use it.

The SDI-12 address of the sensor, the Arduino pin controlling power on/off, and the Arduino pin sending and receiving data are required for the sensor constructor. Optionally, you can include a number of distinct readings to average. The data pin must be a pin that supports pin-change interrupts.

This dataset provides lab-measured soil properties, including soil water matric potential, soil dielectric properties, soil electrical conductivity, corresponding soil moisture. The dataset also includes the basic soil physical properties. Permittivity and soil electrical conductivity measurements were conducted using METER TEROS 12 probes. Soil moisture measurements were made with a TEROS 21 probe. The measurements were conducted in the lab over the span of three years. The purpose of soil collection and lab measurements was to develop an integrated framework that relates the hydrological properties to dielectric properties of permafrost active layer soil in support of the NASA Arctic and Boreal Vulnerability Experiment (ABoVE) Airborne Campaign.

Samples were collected from the surface to permafrost table in soil pits at nine sites along the Dalton Highway in northern Alaska and central regions of Alaska. For the northern slope sites, and from north to south, the sites include Franklin Bluffs, Sagwon, Happy Valley, Ice Cut, and Imnavait Creek. For the central region of Alaska sites, and from west to east, the sites include 8-Mile Lake, Creamers Field, Ballaine Road, and Scottie Creek. Sample collections were made from August 21 to August 27, 2018. Measurements in the lab were made over the span of three years.

The Arctic-Boreal Vulnerability Experiment (ABoVE) is a NASA Terrestrial Ecology Program field campaign being conducted in Alaska and western Canada, for 8 to 10 years, starting in 2015. Research for ABoVE links field-based, process-level studies with geospatial data products derived from airborne and satellite sensors, providing a foundation for improving the analysis, and modeling capabilities needed to understand and predict ecosystem responses to, and societal implications of, climate change in the Arctic and Boreal regions.

Spatial Coverage: Five sites in northern Alaska along the Dalton Highway: Franklin Bluffs, Sagwon, Happy Valley, Ice Cut, and Imnavait Creek. Four sites in central Alaska: 8-Mile Lake, Creamers Field, Ballaine Road, and Scottie Creek.

There are seven data files in comma-separated value (*.csv) format provided with this dataset. The files provide measurements made in the laboratory for 66 soil samples collected in 2018 from 13 soil pits in nine study sites.

For each sample, the measurements cover the entire range of dry to saturation. The number of measurements varied depending on the sample situation. Measurements not made on samples are indicated as -9999.
